Hi there,

Since this was working before, did something change on your PC?

Try running an example from the Multisim Samples folder. In Multisim go to File>>Open Samples>>LabVIEW-Multisim Co-simulation>>Boost Converter.

In the Boost Converter folder you will find a VI and a circuit. Run the VI to see if LabVIEW communicates with Multisim.

What's your exact Multisim version (go to Help>>About Multisim)?

LabVIEW Version?

On my PC, windows10, Labview2017, Mutlsim 14.1, run the summer.vi under the LabVIEW-Multisim Co-simulation folder, I have got error message:


Error -2367 occurred at External Model in summer.vi/Control & Simulation Loop

Possible reason(s):

Control Design and Simulation: The shared library corresponding to the external model returned an error.

Launching Multisim was unsuccessful. (L404)


Any suggestions?

Thanks in Advance
